Scription, re erence being had to the accompanying drawings, forming part of this Speciicationll My invention relates to Athat character of railway' cars having openings through which the contents of the `cars may be dumped therefrom, and doorways for controlling said openings. Ithas been a common practicev and, in 'so far as I amaware, a universal practice in constructingcars of this descrip'- tionto provide a ineans for elevating the dump doors, which is also intended -to'serve as a means y for the support ofthedom's after they vhave `been elevated o1-"closed These constructions Vare objectionable for several reasons, among the `most important of which are the following, namely: should the door elevating-means become broken, or so ilmpaired las to render it an unfit supportfjo'r` the door upheld thereby in its `closed position, the door ispermitted to descend, with a resultant discharge of contents ofthe car. A second objection to `supporting the doors L by the'nieansv vprovided for elevating them is that inasmuch as the doors depend yfor their support upon said elevating means, it is impossible to repair the `elevating means in a loaded' car, in the eventofjim airment thereof, without providing a suita le sup o rtvfor any door connected to the .i impair elevatin means and by which Vthe door may be he d in closed osition durin the period'of time required oro-repair of t e door elevata ing means, f n

My invention has for its object thepro-l vision of, means, aside from the door e1evat ing means, which' is carried by .the frameor body of the car and is. adaptedftc'eiiciently support the dump door, afteritnhas been ele-y va ed by ja ysuitable- .eleyatifig ,means and Whereythe lvatin means is lwholllyrelieved of the. oiiiceo thus overcominghe objectionable features hefeilibefolaisamed-ff Y F'gure I the car body may be dumped.

brackets 41, it is obvious that other means4v of .pivotaly connection between these .members Y may be provided, it being onlyessential that t-he door be soplvotally supported at its inner edge as to provide for it being moved transversely of the car, or towardand away from a side ofthe. car.
